what sort of bhp are you running; if its no more than stage 3 just go for a bailey set up. good quality and not that expensive

easy to fit and will work fine

basically there are 4 take off's on the breather,

2 x take offs, 1 goes to rocker cover (you will need to drill out the cam cover)

the other goes to the where the existing kidney box sits,

smaller bottom pipe returns to the block on the exhaust side of the block

last pipe vents to atmosphere
